SERS spectral probing of dimers of silver nanoparticles molecularly bridged by various molecules
Šmejkal, P.; Vlčková, B.; Moskovits, M.; Pavel, I.; Sládková, M.; Pavlova, Ewa; Šlouf, Miroslav
2006 - English The ability of several molecules to act as linkers for Ag nanoparticles was tested. As new prospective linker molecules, dimercaptocarborane, ethidium bromide and 5,10,15,20-tetrakis(4-sulphonatophenyl)porphine (TSPP) were selected owing to their terminal functional groups, which can assemble the Ag nanoparticles together to form a dimer. Byla zkoumána schopnost několika molekul účinkovat jako spojka Ag nanočástic. Jako nové perspektivní spojovací molekuly byly vybrány dimerkaptokarboran, ethidium bromid a TSPP na základě svých koncových funkčních skupin, které dokáží spojit Ag nanočástice do dimerů.
